Mesothelioma is a type of cancer that develops in the lining that covers the outer surface of some of the body's organs. It's usually linked to asbestos exposure.

Mesothelioma mainly affects the lining of the lungs (pleural mesothelioma), although it can also affect the lining of the tummy (peritoneal mesothelioma), heart or testicles.

More than 2,600 people are diagnosed with the condition each year in the UK. Most cases are diagnosed in people aged 60-80 and men are affected more commonly than women.

Unfortunately it's rarely possible to cure mesothelioma, although treatment can help control the symptoms.
